SPECIFICATION forming part of Letters Patent N 0. 699,467, dated May 6,1902.

Application filed December 18,1901. fierial No. 86,3 90. (N0 model.)

To all whom it may concern:

Be it known that I, CHESTER D. INGRAHAM, a citizen of the United States,and a resident of Penacook, in the county of Merrimack and State of NewHampshire, haveinvented a new and Improved Oarding-Machine Attachment,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improvedcarding-machine attachment for preventing any of the stock from passingover the ends of the cylinder and going to waste and causing all of thestock in the lap to pass to the doifer to insure formation of a lap ofuniform thickness throughout its width.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation ofthe improvement as applied. Fig. 2 is aplan view of the same. Fig. 3 is an enlarged transverse section of partof the improvement on the line 8 3 of Fig. 1, and Fig. 4 is a similarView of the same on the line 4. 4 of Fig. 1.

A carding-machine of usual construction is mounted on a suitable frameA, in which is journaled a cylinder B, operating in conjunction withworkers 0, cleaners D, and a fancy E in the usual manner for carding thefiber of the lap previous to its passage to the dotfer. The attachmentconsists of pairs of revoluble guards F for each pair of workers andcleaners and a pair of larger revoluble guards G for the last worker andfancy. The guards F are located at the ends of the cylinder B and theends of the corresponding workers, cleaners, and fancy to prevent anystock from passing over the cylinder and becoming 10st. The guards F andG are preferably in the form of metal disks having hubs, of which thehubs of the guards F are secured by setscrews or other means to theshafts D of the cleaners (see Fig. 4) to revolve with the same. The hubsof the guards G are secured by setscrews or other means to a transverseshaft G, journaled in suitable bearings arranged on brackets H, attachedto the frame A. On the shaft G is secured a pulley I, over which passesa belt I, connected with a pulley 1 secured on the shaft 0 of the lastworker (l, as plainly indicated in the drawings. Thus when thecardingmachine is in operation the several guards F and G are revolved.By reference to the drawings it will be seen that the guards F aresomewhat larger in diameter than the cleaners D and extend over oroverlap the ends of the cylinder B and the corre* sponding workers 0 toprevent any of the stock from passing endwise over the cylinder andbecoming wasted, and in a like manner the guards G extend over the spaceat the ends of the last worker O, the-fancy E, and the cylinder 13 toprevent loss of stock at this point.

By the arrangement described the lap is not thickened or frayed at theedges, owing to loss of stock, as in machines heretofore constructed;but the lap is kept uniform in thickness to insure a sliver of highquality. It will further be seen that a carding-machine provided with myimprovement need not be stopped very often for removing the waste stockfrom the machine, as'is so often the case in carding-machines heretoforeconstructed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A carding-machine attachment, comprising revolubleguards for closing the spaces at the ends of the cylinder, workers andcleaners, as set forth.

2. Acarding-Inachine attachment,comprising a pair of revoluble guardsforclosing the spaces at the ends of the cylinder, the last worker and thefancy, as set forth.

3. A carding-machine attachment,comprising a pair of revoluble guardsfor closing the spaces at the ends of the cylinder, the last worker andthe fancy, and means for rotating ghe said guards from the last worker,as set orth.

4. Acarding-machine attachment,com.prisname to this specification in thepresence of ing revoluble guards for closing the spaces at twosubscribing Witnesses. I the ends of the cylinder workers and cleaners,the said guards being" in the form of disks CHESTER INGRAHAM 5 securedto the shafts of the cleaners, as set Witnesses:
